Abstract:
The West Link is a double track railway project currently under construction in Gothenburg, Sweden.
The project includes the construction of 8 km of track, 6 km of which will be in tunnels. Next to several
large excavations three new stations will be built: Centralen, Haga and Korsvägen, all within the city of
Gothenburg. The first construction phase of the project began in May 2018, and the finalization of the
project is expected for 2026.
The project is divided into five sections. Keller is involved in four of these contracts assisting the special
foundation works with various geotechnical techniques including Dry deep soil mixing (DDSM), jet
grouting, rock grouting, uplift piles, sheet piling and rock dowels since the design & planning phase in
2018. The core idea behind successful collaboration has been to apply the right product for a location
specific challenge which can help optimise costs & time for the project with a minimal environmental
impact.
Due to the extensive nature of the project, a teamwork of experts from various locations around the
world is helping design and execute various foundation technologies and to provide solutions to the
practical challenges in the project like working close to existing structures, rail lines, river etc.
